Sharing a Passbook card on multiple phones?

[HXGuy]

I didn't think Apple/Passbook would allow for this but I was able to add a $25 Starbucks gift card to both my phone and my wife's, and while we haven't had a chance to test it out, the card shows up on both phones.

Seems great if they actually allow you to share a gift card like this, a lot more useful than just one person having a physical card.

There is no reason why this should not work (just like you could enter the same Starbucks card into multiple instances of the Starbuck app before). Note that Passbook also supports iCloud, i.e. you should be able to sync the cards across multiple devices using the same iCloud login automatically.
